95% confidence interval for ( is (1.8981, 5.3830) Exercise 7.47 (Exercise 7.45, 5th edition) (Hint: in part (a) it is simply asking the confidence interval and use the significance level 0.05. in part (b), do not use formula 7.10 again. Check the large sample conditions and use the large sample confidence interval)

Apr 29, 2013 · Determine and interpret a 90% confidence interval for the mean BAC in fatal crashes in which the driver had a positive BAC. The 90% confidence interval for the mean BAC is (0.147, 0.153). Round to the nearest thousandth. We are 90% confident that the mean BAC in fatal crashes in which the driver had a positive BAC is in the interval (0.147, 0.153).

If using a computer package, it will normally report both the Chi square and the probability or significance level corresponding to this value. In testing your null hypothesis, REJECT if the reported probability is less than .05 (or whatever confidence level you have chosen). FAIL TO REJECT if the probability is greater than .05.
